检查下面的例子它应该工作 

@Override
protected void onCreate(Bundle savedInstanceState) 
{
   super.onCreate(savedInstanceState);
   setContentView(R.layout.activity_main);
   init();
}
private void init()
{
    //your webservice envelope
    String envelope="<?xml version=\"1.0\" encoding=\"utf-8\"?><soap:Envelope     xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\"><soap:Body><GetContentTreeBySections xmlns=\"http://tempuri.org/\"><SectionsInclude>%s</SectionsInclude><DocumentCount>%s</DocumentCount><SortBy>%s</SortBy><SortOrder>%s</SortOrder><UserName>%s</UserName><Pass>%s</Pass></GetContentTreeBySections></soap:Body></soap:Envelope>";

String myEnvelope = String.format(envelope, "myParam1 value", "myParam2 value","myParam3 value","myParam4 value");
String url = "http://www.mywebserice.com/XMLGenerator/GenerateXML.asmx";
String soapAction = "http://tempuri.org/GetContentTreeBySections"; 
String response = CallWebService(url, soapAction, myEnvelope);
//Log.v("response", response);
Toast.makeText(getApplicationContext(), "this"+response,Toast.LENGTH_LONG).show();
String xml=response;    
}

@Override
public boolean onCreateOptionsMenu(Menu menu) 
{
   // Inflate the menu; this adds items to the action bar if it is present.
   getMenuInflater().inflate(R.menu.activity_main, menu);
   return true;
}
  String CallWebService(String url,String soapAction,String envelope) 
{

  final DefaultHttpClient httpClient=new DefaultHttpClient();
  // request parameters
  HttpParams params = httpClient.getParams();
     HttpConnectionParams.setConnectionTimeout(params, 10000);
     HttpConnectionParams.setSoTimeout(params, 15000);
     // set parameter
  HttpProtocolParams.setUseExpectContinue(httpClient.getParams(), true);

  // POST the envelope
  HttpPost httppost = new HttpPost(url);
  // add headers
     httppost.setHeader("soapaction", soapAction);
     httppost.setHeader("Content-Type", "text/xml; charset=utf-8");
     String responseString="";

     try 
     {
            // the entity holds the request
            HttpEntity entity = new StringEntity(envelope);
            httppost.setEntity(entity);

            // Response handler
            ResponseHandler<String> rh=new ResponseHandler<String>() {
    // invoked when client receives response
    public String handleResponse(HttpResponse response)
      throws ClientProtocolException, IOException {

     // get response entity
     HttpEntity entity = response.getEntity();

     // read the response as byte array
           StringBuffer out = new StringBuffer();
           byte[] b = EntityUtils.toByteArray(entity);

           // write the response byte array to a string buffer
           out.append(new String(b, 0, b.length));
           return out.toString();
    }
   };

   responseString=httpClient.execute(httppost, rh); 

  }
     catch (Exception e) {
      Log.v("exception", e.toString());
  }

     // close the connection
  httpClient.getConnectionManager().shutdown();
  return responseString;
}
